Why is the incidence of cardiovascular and cerebrovascular diseases high in autumn and winter?

Autumn and winter seasons are the high incidence of many diseases, especially cardiovascular and cerebrovascular diseases. Then, why are the cardiovascular and cerebrovascular diseases in the autumn and winter seasons high, and what should we pay attention to?

First, the cold is easy to cause cardiovascular and cerebrovascular diseases

The main reason for the high incidence of cardiovascular and cerebrovascular diseases in autumn and winter is that cold can cause body vasoconstriction and reduce sweating, thereby stimulating blood pressure. The human body will have sympathetic excitation, rapid blood flow, increased peripheral resistance of blood vessels, resulting in elevated blood pressure or vascular embolism. In addition, the amount of activity of people decreases during cold weather. The blood perfusion of the brain, myocardium, and viscera is also reduced, which is one of the causes of high incidence of cardiovascular and cerebrovascular diseases.

Second, how to prevent cardiovascular and cerebrovascular diseases in autumn and winter

1, reasonable diet is conducive to prevention of cardiovascular and cerebrovascular diseases

Cardiovascular disease prevention and treatment should have reasonable dietary arrangements. Hyperlipidemia, unbalanced diet, diabetes and obesity are all related to dietary nutrition. In principle, it should be “three lows”: low calorie, low fat, low cholesterol. And actively control weight through a reasonable diet. Studies have shown that weight gain is 10%, coronary heart disease risk is increased by 38%; weight gain is 20%, and coronary heart disease risk is increased by 86%. Therefore, diet control is an important condition for prevention of cardiovascular and cerebrovascular diseases.

The correct diet for patients with cardiovascular and cerebrovascular diseases should be light, and eat fresh green leafy vegetables and seasonal fruits. Increase fiber diet, that is, eat more coarse grains, dried beans, vegetables, fruits and so on. Minimize the intake of fat and cholesterol, such as the brain, internal organs, and egg yolk of animals. Some people think that seafood is safer. In fact, some seafood have higher cholesterol levels, such as crabs and scaleless fish. These seafoods should be eaten less. In general, foods that protect the heart and brain are: glutinous rice, kelp, celery, fungus, oatmeal, beans, spinach, walnuts, almonds, etc., should be eaten in daily life, these foods contain a lot of VE and VB6.

2, proper exercise is conducive to prevention of cardiovascular and cerebrovascular diseases

The cold weather in autumn and winter, many people have reduced outdoor activities, and the habit of eating big fish and meat on the diet can easily lead to a significant increase in weight. Obesity is easy to induce high blood pressure. If blood pressure is not well controlled, let it develop, then some very dangerous diseases such as myocardial infarction, sudden cardiac death, etc., will come to the door.

Prevention and treatment of cardiovascular and cerebrovascular diseases should actively participate in appropriate physical exercise. Regular and appropriate exercise is conducive to enhancing heart function and promoting normal metabolism of the body. Appropriate amount of physical activity helps to improve blood circulation, enhances resistance, increases the oxygen content of various organs, and functions throughout the body. While taking appropriate exercise, you can also take some drugs that increase myocardial oxygenation, which not only helps to improve blood circulation, but also significantly improve the body’s ability to resist hypoxia, especially increase myocardial oxygen content, and better prevent heart and brain. Vascular disease.

Some old people like to get up early morning exercise, but the morning of autumn and winter is the lowest temperature in the day. Just come out from the warm bed, go to the outdoor, the temperature difference is too big, the cold will make the cardiovascular contraction, it is easy to cause disease. For cardiovascular patients, it is important to keep warm during the fall and winter seasons. Generally speaking, if time permits, especially for the elderly, you can go outside at 3 or 5 in the afternoon and do some proper exercise. It is even more important to control the amount of exercise and not to burden the heart.
